In honor of this xkcd comic (https://www.xkcd.com/1313/), I made these regexes.
/[ckp]e|j| t/
Matches: The subtitles of each Star Wars movie (yes, even "The Force Awakens" and "The Last Jedi")
Doesn't match: The subtitles of each Star Trek movie
Special notes: The Star Trek movie without a subtitle isn't counted, as it does not have a subtitle.
/f?i.?[ns]|h |y/
Matches: The subtitles of each Star Trek movie
Doesn't match: The subtitles of each Star Wars movie
Special notes: The Star Trek movie without a subtitle isn't counted, as it does not have a subtitle.
/[jt]o|[lm][as]|n[ae]|r.e|dr/
Matches: The last names of US Presidents who were Democrats
Doesn't match: The last names of US Presidents who were Republican
Special notes: Franklin Delano Roosevelt is rendered as "fdr".
/g|s[eh]|o[lor]|.[kpx]|^[ht]?a/
Matches: The last names of US Presidents who were Republican
Doesn't match: The last names of US Presidents who were Democrats
Special notes: Franklin Delano Roosevelt is rendered as "fdr".
Can anyone optimize these/make others?
BUSTED - this does not work. You are now busted.

What doesn't work? And how? I have tested these with all acceptable inputs.
Oh ok. I guess they must work then. I stand corrected.
I have a few, will be posting in a week when I get home (on vacation :/)
I have a few challenges.
I am looking for RegEx statements that...
-accept the names of the top 5 renewable energy sources, but reject the top 5 non-renewable ones
-accept the capital cities of US states, but reject the names of the states (i.e. "Columbus" would pass, but "Ohio" would not)
I'll post more challenges as I think of 'em.
Top 5 renewable energy sources:
Hydropower, Biomass Wood, Biomass Waste, Biomass Biofuel, Wind
Top 5 non-renewable energy sources:
Coal, Petroleum, Natural Gas, Nuclear Energy, Fossil Fuels
Match non-renewable but not renewable:
/c|[ms]$/
Match renewable but not non-renewable:
/b|w/
And here's a badly-done regex golf of the states/capitals problem.
Match states but not their capitals:
/[aio].a.{0,3}$|^[gku-w]|^m[ai][^d]|^[npt][e]|^[or]\
|i(cu|fo|no)/[/tt]
Match capitals but not their states:
